Patent No. 279,334, dated June 12, 1883,

Application tiled February 20, 1883. (Model.)

T0 a/ZZ whom it may concern.-

Be it known that I, CnARLEs CLARK, of Smyrna, in the county ofRutherford and State of Tennessee, have invented a new and usefulImprovement in Door-Bolts, of which the following is a full, clear, andexact description.

' Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures` Figure l, Sheet l, is afrontelevation, partly in section, oi' my improvement. Fig. 2, Sh'eet l, is asectional plan view of the same, taken through the broken line x x a:of, Fig. l. Fig. 3, Sheet 2, is a sectional elevation ot' the same,taken throughA the line 1/ y y y, Fig. l.

The object of this invention is to promote security and convenience infastening doors.

The invention consi'sts of a combination and rods wherein the wheel oi'lone part of a double door has an angular recess formed in its side toreceive the angular end of a bolt of the wheel of the other part of thedoor, whereby the bolts of one part of the door will be locked by thebolts of the other part ofthe said door. In the boltoperating wheel isformed a recess to receive the end of a locking-lever, held against thesaid wheel by a spring to adapt the bolts to serveas outside fastenings,as will be hereinafter fully described.

I will describe my improvement as applied to double doors, but l` do notlimit myselt' to that use, as it can be applied lwith' equal advantageto single doors.

A A represent the parts oli' a double door, which are hinged todoor-posts in the ordinary manner. To' the middle forward parts ot' thedoors AA' are secured boxes or cases B B', which have slots in theirsides for the passage of rods C C'. The rods C C' haveoutwardlyprojecting hooks upon both ends. The hooks at the inner ends ofthe rods C (.1 pass through the saine distance from the centers of thesaid Wheels and at equal distances from each other. The wheels D D' aresupported above the rods C C' byihubs or washers E E', formed upon thesaid wheels or interposed between the said wheels and the bottoms of thesaid cases B B', so that the rods C C' and the wheels D D' will sidefastenings.`

work freely. rllhe wheels D D are rigidly connected with the shafts orspindlesF F',-

are attached only to the outer ends of the spindles F F', as shown inFig. The outer ends ofthe rods C C' are hooked into holes in bolts H H',which are recessed upon their inA ner sides to receive the said rods 5or the bolts and rods can be connected in any suitable manner. Therecesses inthe bolts H H' are iiared or inclined to allow the rods C` C'to move freely as they are brought into inclined positions by turningthe wheels D D'. The

bolts H H' are kept in place and made to move in straight lines as theyare thrown and withdrawn by keepers I I', attached to the doors A A'.The door A' has but three bolts H', and the side of the wheel D next thefree edge oi' the said door A' has an angular recess, J, formed in it,to receive the angular end ot the bolts H, that shoots acrosstheadjacent edges of the doors A A' and moves through strong keepers orsockets 4l K', attached to the adjacent parts ofthe said doors. Thewheels D D' are held from being turned in the wrong direction by pins LL', attached to the doors A A' or the cases B B', for the rods C C' tostrike against; In 'the side of the wheel D is formed a recess, M, toreceive the bent inner end ot the lever N, which is pivoted to the caseB, and is heldi'orward against the wheel D by a spring, 10, attached toit and to'thc said ease D. rPhe outer end of the lever N projects intosuch aposition that it can be reached and operated by the bit of a key,I), inserted through a key-hole, Q, in the door A.

Having thus fully described my invention, I claim as new and desire 'tosecure by Letters Patentl. In a door-bolt, the wheel D', having angularrecess J, rods C', and bolts H', in com- ICO buatou with the bolts H,one having ou aunotch or recess M, and angular lever N, subgulalrpointed end, rods C, and. Wheel D, substantially as and for the purposeset forth. stantially as and :for the purpose set forth.
